Pairing/Bonding with third party weight scale

[OldisGold]

Hi all, First of all thanks for Nordic team for the excellent support. It is very useful for a beginner like me to get started on BLE development.

I am using the nRF51422 DK board to connect to a third party weight scale. The weight scale connects to an android app in a two stage process. The first step is used to pair/bond to the phone and then the weight scale powers off. When a person steps onto the weight scale it takes a reading and then transmits once the measurement process is complete. The bluetooth on the phone is always on during the entire process.

I am now using the nRF51 dk board to connect to this weight scale. I have connect PO.30 to ground and i can discover other ble devices on the master control panel.

Questions:

When I connect to the weight scale, I am not able to see the characteristics for weight measurement (0x2A9D), weight scale feature (0x2A9E) in the Master Control Panel. Am I missing something ? ref: developer.bluetooth.org/.../CharacteristicsHome.aspx

Assuming the third party weight scale is using the bluetooth service for weight scale ref: org.bluetooth.service.weight_scale

Also I want to know if it is possible to connect to other similar health monitoring third party devices using nRF51422 DK ?

PS: I searched the forums for a similar question but couldn't find anything related to a pairing/bonding to a third party weight scale.

If you are building for 3rd party devices, reach out to the manufacturer to get more information, learn about the traffic send on the air by using nRF Sniffer. Assuming a 3rd party is using a standard Service may be incorrect and you need to verify that assumption.

I can sniff data packets using nRFSniffer. I am following up with the manufacturer to find out the profile used in the device. If different devices use different profiles should i look for that particular service that transmits data in each device ?
